loopback-mixin-cache

Redis cache mixin for LoopBack

loopback-mixin-cache adds easy to use redis caching to any of your models.

Installation

$ npm i loopback-mixin-cache --save

Config

Server Config

With loopback-boot@v2.8.0 mixinSources have been implemented in a way which allows for loading this mixin without changes to the server.js file previously required. Just add "../node_modules/loopback-mixin-cache" to the mixins property of your server/model-config.json.

{
  "_meta": {
    "mixins": [
      "loopback/common/mixins",
      "../node_modules/loopback-mixin-cache",
      "../common/mixins"
    ]
  }
}

Model Config

To use with your models just add Cache: true to mixins in your model config and the default options will be used:

{
  "name": "Model",
  "properties": {
    "name": {
      "type": "string",
    }
  },
  "mixins": {
    "Cache": true
  }

  ...

  // you can also overide the default values:
  "mixins": {
    "Cache": {
      "ttl": 30    // time to live (how long an item is being cached), default: 120
    }
  }
}

Global Config

It is also possible to configure the mixin globally in your config.json. Just add cache and use the same options as with the model above:

{
  "cache": {
    "ttl": 30    // time to live (how long an item is being cached), default: 120
  }
}

ToDo and ideas

• optimize cache keys
• add override parameter (e.g. ?noCache=true)
• add better usage documentation to this readme (e.g. noCaheFlag)
• find better solution for searching and deleting cached items
• add response headers with information about the cache (environment agnostic)
